SHAFT-BUSHING.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed December 17, 1909. Serial No. 533,535.

b all whom it may concern Be it known that I, Annxnnnnn RANKnin- LOR, ofSaco, in the county of York and State of Maine, a citizen of the UnitedStates, have invented a new and useful Improvement in Shaft-Bushings, ofwhich the following is a specification.

My present invention relates to a bushing especially adapted for use insupporting a long shaft where there may be a tendency on the part of theshaft to In such cases where the shaft supported in the samsons oruprights on which the machine is built and passes through openingstherein bushings are used in such openings, and it is desirable thatsuch bushings be capable of self-adjustment according to therequirements of the shaft.

My invention consists in a bushing which will. aline itself with theshaft and may provide simple means of applying lubrication and while itis held in place in the support it is easily removable so that the shaftmay be withdrawn if desired.

My invention will be understood by reference to the drawings in which aform thereof is shown.

Figure 1 is a plan partly in section of one form of bushing comprisingmy invention, F 2 being a vertical section on line 22 of Fig. 1.

In all the views A is the shaft and B is the samson or upright. In eachform of my invention the Samson is provided with an opening within whichis the bushing C through which the shaft passes. Either the samson orsupport or the bushing, or both, is cut away to form a clearance betweenthe surface of said bushing and the wall of said opening, and extendingto the end of said opening, so as to allow the bushing to rock 01'settle itself in place in the support according to the requirements ofthe shaft. As herein shown both of said parts are so formed. The openinghas a flange or collar comprising a bearing 7) for the bushing whichbearing surface is short with relation to the length of said bushing,and a portion 6 which is cut away or of larger diameter than the bushingso as to provide the clearance above referred to. The outer edge 6 ofthis clearance section serves as a stop to engage a correspondingportion of the bushing and assist in holding it in place.

The outer surface of the bushing C comprises what may be termed asupporting or bearing section 0, which fits the bearing Z) of thesamson, a section cut away or reduced in diameter to contribute to theclearance above mentioned, and a stop section a" of slightly largerdiameter than the largest diameter of the clearance 71 in the samson.The face 0 of the stop section is finished to engage the edge I) of theclearance at the exterior face of the support, and it serves to preventthe bushing from being driven too far into the sanison when the bushingis put in place. The bushing is kept from enclwise movement: by a collarI) which is preferably clamped on the shaft A by a screw (1. The bushingC is provided with a spout E which is either cast integral with it asshown, or which may be made separately and screwed into the bushing. Inthe former case it provides an oiling passage 0 which leads to the shaftA for lubrication purposes, and in the latter the passage through itregisters with an opening 6 in the bushing itself for the same purpose.But in addition this spout serves to keep the bushing from rotation. For this purpose in the form of my invention shown in Figs. 1 and 2 anopening E" is provided in the samson into which the spout E sets whenthe bushing is in place. This opening is su'lliciently large to allowthe bushing to settle itself into position but not large enough to allowthe spout and bushing to turn.

Other varieties of this construction will occur to those skilled in theart.

\Vhile the support for the bushing is referred to as a samson it may beany other stationary part, for example, a bracket or hanger.

I have referred to the spout as being perforated or provided with apassage therethrough for lubricating purposes, but if it is not soprovided it may still act as a projection to prevent the rotation of thebushing. Moreover l[ have shown the clearance between the bushing andsupport as made partly from the bushing and partly from the support.Instead it may be made entirely either from the support or from thebushing if through best.

hat I claim as my invention is The bushing above described having abearing section, a clearance and a stop section, said clearance beinglocated between movement With relation to said support,

said bearing section and said stop section, in said means comprising ashaft and a collar comblnatlon With a support having aporlocatedthereon.
